Mike Machado replied to Jon von Weymarn's discussion Telemetry to Turnigy 9X (with FrSky FLD-02 Telemetry Display Screen)"Voltage comes directly from the mavlink feed. In fact, we dont even have the individual cell voltages, we fake it by dividing based on number of calculated cells. So that means if the voltage is off, APM is giving it the wrong value. Most likely…"

I just tested the firmware, 4S is now reading correctly however the voltages are not correct. The display is showing the 4S battery as being around 15.5v however it it is almost nearly fully charged. I put it the battery on the charger…"

Mike Machado replied to Jon von Weymarn's discussion Telemetry to Turnigy 9X (with FrSky FLD-02 Telemetry Display Screen)"Give the attached hex a try. Ive never distributed a build like this, so hopefully I found the right .hex file.
As for building, the technique is similar to building ArduPilot. Basically the trick is to checkout the github code, and then open…"

I don't suppose you happen to have the file as a hex or could give me some quick instructions on how to upload the .ino. I have tried in Arduino 1.0.3 but it errors on the Title line of the code. I am probably doing something…"

DIY 3RD quad carrycase out of wood and an old mattress
Posted on January 2, 2013 at 1:30pm 3 Comments 4 Likes
Hi all,
Just thought I'd post pics of my quad case. It took a while to build but the cost to build it was practically zero. I utilized an old beds plywood and the foam from its mattress.
I have been using it now for about 4 months and I really like it. It's just big enough to securely fit:

The solution is a bit of an anti-climax so in short:
I got Loiter to work by re-flashing the firmware.
The longer version:
I built the quad which was a 3DR ArduCopter Quad-B. Everything seemed to work like a charm. It flew like a dream in…

So I'm flying up at 120m. What then happens is every RC pilots nightmare! Power cuts off from the APM!
Quad drops to about 90m before it wakes up again, then I take it down crazyfast but controlled to 20m, then at 20m it dies again and drops like a rock... hits pavement...3 broken props, all landing gear, 2 bent…
